New to scouts but picked up a 67' scout 800 with a 152 and it has the large brake drums. I have to redo almost every system and I will be starting with the brakes. I want to upgrade to a dual master cylinder but noted that some seem to dislike the 1" bore M/C due to soft brakes. The original single M/C has a 7/8" bore so perhaps that would be a better way to go just in a dual configuration. Any help/comments would be great. Thanks, Don B.
